Abstract Predictive PI (PPI) Controller was introduced in (A.B. Rad, W.L. Lo, Predictive PI controller. International Journal of Control 60 (5) (1994) 953–975. The purpose of this paper is to introduce an enhanced PPI (output predictive PI controller) which overcomes the problems of large control action and derivative kick, which may arise in some situations. The practical problem of auto-tuning of the output predictive PI controller is also considered in this paper. The performance of the new auto-tuning output predictive PI controller is demonstrated and compared with a commercial PID auto-tuner.
